Abstract

PURPOSE:To permit a bogie to change the direction freely in curve travelling, by connecting a cross beam with less high torsional rigidity to a spherical joint and V-groove with curved surface in projected mating at two points in the front and the rear of a couple of bogies, right and left. CONSTITUTION:A bogie 1 is arranged opposite a pair of rails 4, right and left, for magnetic levitation provided on an sleeper 3 arranged on a track beam 2 at suitable intervals. This bogie 1 is connected with a hinge of spherical joint 6 at its upper end at two points in the front and rear. At its lower end it is abutted on bogie 1 side to V-groove 1a and on cross beam 5 side taperedly to a curved surface 5a. Thus, along with reduced rigidity, it turns out the structure to allow the torsion of the bogies 1, right and left, without warping the position to the rail 4 for magnetic levitation of the bogies 1, right and left.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a vehicle with multiple or more sets of bogies,
The present invention also relates to a flexible bogie structure for a linear motor car that is levitated by a magnetic levitation magnet and propelled by a linear motor.

[Prior art]

Conventional bogies placed against the left and right rails are separated on the left and right sides, as shown in Figures 1 to 3, and each has its own shock absorbing mechanism to maintain its posture and absorb the load. It was configured to load.

[Problem that the invention seeks to solve]

In the conventional trolleys mentioned above, in order to maintain the posture of each individual trolley, the mechanism becomes complicated and the number of parts is also increased, as shown in Figure 2. (Since it faces directly to the vehicle body, there was a drawback that the vehicle body was tilted (as shown in FIG. 3) and the attitude of the module with respect to the rails was distorted.

[Means for solving problems]

The present invention was devised to solve this problem in view of the above circumstances, and includes a magnetic levitation magnet, a propulsion linear induction motor, a brake, and a landing skid for each of the left and right magnetic levitation rails. , a secondary shock absorbing spring, and other equipment are integrated into one! In a linear motor car in which bogies are arranged 11-fpDm so as to face each other, as shown in FIG.
At the upper end, a cross beam with low torsional rigidity is connected with a spherical joint as shown in FIGS. 10A and 11, and at the lower end, a bogie structure is formed in which the groove and curved surface abut against each other.
As shown in Figures 5 and 6, the configuration is such that the posture is maintained by constantly generating a clockwise moment, and a mechanism is added that does not impede other degrees of freedom. The purpose is to twist the cart of time and gain the freedom to change direction.

〔Example〕

Next, the flexible bogie structure of a linear motor car according to the present invention will be explained with reference to the drawings.

In FIG. 4, reference numerals 1 and 1 indicate a bogie, which is disposed facing a pair of left and right magnetic levitation rails 4, 4 provided on sleepers 3 arranged at appropriate intervals on a track girder 2. As shown in FIGS. 7A and 7B, 1 has two parts, the front and the rear, and the upper ends are connected by a hinge of a ball joint 6 as shown in FIG. 10A, and the lower end has a groove 1a on the side of the truck 1. The side of the cross beam 5 is tapered so that they abut against each other as a curved surface 5a, so that the left and right carts 1, 1 can be easily moved without disturbing the posture of the left and right carts 1, 1 with respect to the magnetic levitation rails 4, 4, as well as the torsion of the cross beam 5, which has low rigidity. 1,1
The structure allows for torsion, and the torsional deformation between the transition curves as shown in FIGS. reactor.

A movable platform 8 supported by air springs 7 is arranged at the front and rear of the left and right bogies 1, 1 (as shown in Fig. 6), and a vehicle is mounted via linear bearings 9, 9 on the movable platform 8. .

[For production]

As is clear from the above structure, the left and right bogies 1, 1 are connected to the cross beam 5 at two points at the front and rear, respectively, at the upper end by a hinge of a ball joint, and at the lower end, the groove 1a and the curved surface 5a are butted. This, combined with the torsion of the lower rigidity cross beams, does not disturb the posture of the left and right bogies relative to the rails.
Furthermore, the structure allows for twisting of the left and right platforms by $1.1, allowing deformation corresponding to the transition curve, and freedom is provided by the spherical joint, allowing the direction of the bogie to be changed freely when traveling on curves.

〔effect〕

As mentioned above, in a linear motor car, the present invention connects cross beams with low torsional rigidity at two locations at the front and rear parts of a pair of left and right bogies with a ball joint at the upper end, and connects one side with a groove at the lower end. and the other is a flexible bogie structure in which the curved surfaces abut against each other, and the left and right bogies can be supported without being disturbed in their posture with respect to the rail even when the jet beams are twisted.Moreover, this spherical joint, It has features such as being able to move freely, deform in transition curves, and change the direction of the bogie when traveling on curves.
